Preheat your oven to 350°F, and line your cupcake pan with cupcake wrappers.
In a stand mixer with the paddle attachment, cream together the butter and sugar until fluffy.
Add eggs and vanilla, mix well.
In another bowl, whisk together all of the dry ingredients.
Add dry ingredients slowly to wet ingredients being sure to mix completely between each addition.
Stir in the milk and combine.
Using a large cookie scoop, fill the cupcake liners ⅔ full.
Bake for 20-25 minutes or until a toothpick inserted into the middle of a cupcake comes out clean.
Let cool in pan for a few minutes then remove the cupcakes to a cooling rack to cool completely before adding the frosting.
How to Make the Chocolate Frosting
In a large bowl, using an electric mixer, combine the butter, cocoa, milk, and vanilla.
Add the powdered sugar and mix well.
If the frosting is too dry, add a tablespoon or two of milk and mix. If it is too runny, add a small amount of powdered sugar.
Repeat either of these until you reach the desired consistency for your frosting.
How to Decorate the Cupcakes
Spread the frosting on the top of each cupcake using either the back of a knife or an offset spatula.
You can even use a pastry bag fitted with a decorative swirl tip.
To make your reindeer face, use two pretzel twists for antlers, candy eyes, and red M&M's for the nose.
Notes
Spray the paper muffin cups with non-stick cooking spray before adding the cupcake batter. This will help the baked cupcake not stick to the paper muffin cups.
Make sure the cupcakes are cooled completely before adding the frosting or the frosting will begin to melt.
